Phylogenetic relationships between tuco-tucos (Ctenomys, Rodentia) of the Corrientes group and the C. pearsoni complex
Lineage delimitation is of extreme importance in evolutionary biology and constitutes an essential tool in basic and applied fields including conservation. We addressed the delimitation of two closely related species complexes of South American rodents of the genus Ctenomys (tuco-tucos), namely the...

Lineage delimitation is of extreme importance in evolutionary biology and constitutes an essential tool in basic and applied fields including conservation.
